Actress Jada Pinkett Smith jetted to Washington, D.C. on Tuesday to testify before Congress about the need to combat human trafficking.

The star, accompanied by her movie icon husband Will and 11-year-old daughter Willow, met with officials on Capitol Hill during a Senate Foreign Relations Committee meeting and appealed to legislators to step up their fight, arguing, “Slavery robs us of the thing we value most: our freedom.”

The 40-year-old also announced plans to launch a new campaign to help victims, according to the Associated Press.

Willow Smith took to Twitter.com about her time in the U.S. capital, sharing a photo of herself seated behind one-time U.S. presidential nominee John Kerry’s placard and tweeting, “I’m getting radical on human trafficking.”

This isn’t the first time Pinkett Smith has spoken out against the illegal trade of human beings – she recently teamed up with fellow actress Salma Hayek to make a new video for the Don’t Sell Bodies campaign, which fights against the exploitation of women and children around the world.
